Tried the knoppix testcd cheatcode on my hp pavilion zv5000 and knoppix froze even before the test could take place. I then tested the CDs on the laptop that successfully loaded knoppix before and all the disks passed the test.

-Edit-
Don't know exactly what this means but after reading how some people had success with earlier versions of knoppix and then had trouble moving to 5.0.1 I tried knoppix 4.0.2 and it loaded fine.
